Information about rate-limiting/bandwidth-estimation/congestion-control #1922

Description

@qwertzui11

Summary

I'm evaluating pine. One requirement is an adaptive video-bitrate, depending on the available bandwidth.

Motivation

If I encode a video at 6mbit/s but the bandwidth only allows 2mbit/s, buffers will overflow and frames drop.
To avoid frame-drops, I'd rather change the bitrate on the encoder and/or lower the resolution.

I'd like to get some information at some point, if I've got to lower/raise the quality of a video stream.
Is that possible yet? If so, how? Could you point me to some example or documentation? Shall I use the stats. I guess Congestion Control is the desired solution, which is not implemented yet?

Describe alternatives you've considered

I used Googles Webrtc implementation which tells an Encoder, using the method SetRates, at what rate the encoder should deliver frames. Here's an implementation

Thx for your time. So far pion is an awesome experience 😍
